[ITK] [ITK-users] built opencv bridge but can't find

[Tammy Diprima]

Hi Matt,

Thank you for the advice.  You're right, in that I need not include any
OpenCV dirs; it's all about ITK.
The problem is, I'm already doing the:

find_package( ITK REQUIRED )
include( ${ITK_USE_FILE} )

The compiler's not happy unless I physically copy the header and source
files (itkOpenCVImageBridge.*) from [
ITK-SOURCE-DIR]/Modules/Video/BridgeOpenCV/include to a location CMakeLists
knows about (in an include directory).  Which makes sense, but I would have
thought when I built ITK with the BridgeOpenCV flag turned on that it would
have been copied during that particular process.  Oh well.  At least it's
working now.

Cheers, thanks a lot.
Tammy
